CULTIVATOR ATTACHMENT FOR DOUBLE-SHOVEL PLOWS.

SPECIFICATION forming part of Letters Patent No. 441,592, dated.November 25, 1890.

Application filed July 16, 1890- Serial No. 358,908. (No model.)

To all whom it may concern.-

Be it known that I, RILEY D. SNYDER, a citizen of the United States,residing at Avon, in the county of Hendricks and State of Indiana, haveinvented a new and useful Cultivator Attachment for Double-Shovel Plows,of which the following is a specification.

This invention has relation to a cultivator attachment for double-shovelplows; and the objects of the invention are to provide means forsecuring to the plows a series or gang of cultivator-teeth, to soarrange the teeth as to require but light structural support, and torender the entire attachment simple, cheap, and effective.

With the above general objects in view the invention consists in certainfeatures of construction hereinafter specified, and particularly pointedout in the claims.

Referring to the drawings, Figure 1 is a perspective of my attachment,the same being applied to a double-shovel plow of the ordinaryconstruction. Fig. 2 is a detailin perspective of the attachment, thesame being enlarged. Fig. 3 is a detail in perspective of the jointbetween the sections.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In practicing my invention I employ a cultivator-bar 1, preferablyformed of bar-steel and divided into two sections, designated as 2 and3. These sections are adjustably connected in the present instance bymeans of a slot 4 being formed in the section 2 for the passagetherethrough of a transverse ad justing-bolt 5, which passes throughsaid slot and also through the section 3. The righthand ends of the twosections are bent at an obtuse angle to said sections, as at 6, andintermediate their ends each section is provided with an offset 7. Theoffsets 7 and bent portions 6 of the sections are each pro: vided withrecesses or seats 8 for the reception of the cultivator-teeth 9, andsaid teeth are held in position within their seats by means ofbinding-bolts 10. In forming the bends of the offsets the lines of thebends are inclined, and not directly across or at a right angle to thelongitudinal edge of the bar 1, so that the said bar 1 conforms to theinclination of the depending shovel-standards 11, which extend from theplow-beams 12 of an ordinary double-shovel cultivator. The offstandards11 and are connected by tie-plates 14, which are bound upon thestandards by means of nuts applied to the ends of the bolts.

By my invention it will be apparent that I am enabled to transform anordinary doubleshovel plow into an efficient cultivator, the teeth ofwhich are arranged one in advance of the other and slightly to one side,so that each succeeding tooth acts to fill the furrow formed by thepreceding tooth, as is evident. The disposition of the cultivator-bar issuch' that light metal may be employed,in that the draft or strain isnearly in line with the bar instead of at a right angle to it, as isordinarily the case.

Having thus described my invention, what I claim is- 1. Theherein-described attachment for double-shovel plows, the same comprisinga cultivator-bar formed in opposite overlapping sections adj ustablyconnected and arranged in line with each other, forming a continuousbar, each section provided with ofli'sets having recessed tooth -seats,cultivator teeth mounted in the seats, bolts passing through the teethand the seats, and each section provided with devices for fastening thesame to a plow-standard of adouble-shovel plow, sub stantially asspecified.

2. The herein-described harrowattachment, the same consisting of a pairof barrow-bar sections arranged in line with and overlapping each otherand forming a continuous bar, one of said sections being slotted and theother provided with an adjusting-bolt for engaging the slot, each ofsaid sections being provided with offsets forming tooth-seats and thefront section having its inner end bent or deflected from the rearsection and forming an offset, and teeth secured within said offsets,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.

RILEY D. SNYDER.
